- To all whom it may concern: 1

. .Be it known that I, TRUMAN arm-5 a citizen of theUnited.States,-residing3.at

Dallas, in the county of; Dallas and. Stateof Texas, :have invented. new and usefulImprovements in Steam-Boilers, of which the follow-ingiis a specification- I; I

- This invention relates tosteam boilers and alms to provide means" whereby the heat from the firebox. will 1;bedirected around the walls of the, waterchamberin-a i the: construction bein such as'to; directsthe mannerto'traverse the entire area of'said Wail-1817' 1' r i I H i I 'Another object of'the is topror V viderm'eans for positioning the water cham her: so that all of its. walls will. be exposed,

heat as it leavestheflrefbox aroundtheline side wall of thetwateri chamber, the draft causingthe heat to traVelarOund and contact with the outside walls of said chamber before reaching the atmosphere.

I The invention further consists ofthe novel malinerof constructing" the boiler so as to permit of convenient access to the water chamber for cleaning the same, the said chamber being also removable in order -tocombination and arrangement of parts,

hereinafter more fully described and illustrated 'in the accompanying drawings, in which Figure l'is a front elevation of a boiler constructed in accordance with'the present invention;

Fig. 2 is a vertical longitudinal sectional view on the line 2 2 of Fig. 1;

r Fig. 3 is a vertical transverse sectional view on the line 33 of Fig. 2;

Fig. 4 is a detail sectional view on the line 4-4 of Fig. 2; and

Fig. 5 is a fragmentary sectional view on the line 55 of Fig. 2. V

Referring to the drawingsin detail, similar characters. of reference denote corresponding parts throughout the several views.

In the drawings, there'is-illustrated, a

boiler which may be of the locomotive or stationary type, the invention being susceptible of application to boilers of either form. This boiler includes 'a water chamberlO composed of spaced walls .11 and 12, the= mmonses; 1

latter wall being spaced. within the former asillustratedin the drawings. E 1Th's water chamber is mounted within. the preferably. cylindrical casing 13, which is spaced afromithe outer wall 11 of the chamber "10, sofas to provide a passage 14 entirely surrounding the water chamber.

Thecasing 13 has spaced therefrom upon the inside',a wall-'15, which contains aidead air "spacer16to provide an insulation to prevent-the escape of heat through lthe casing'1 3J The'casing 13: may be formed in any suit'able manner and if desired maybe further insulated byproviding spaced inner, and outer walls17 and 18, the space between these .wallsbeing filled with suitable insulatingmaterial19; I

' The casing 13 may be supported in suitable manner in accordance with the type of boiler, so thatitjisfnotdeemedmecessary to illustrate the supports-of the same.

Located within the space formed by the v inner wall 12 isv 'a fire box 20, a grate 2 1;and an ash pit 22, :so that a; suitable source of heat may be provided for heating the water vwithin the'chamber 10;. :Thissourceofheat -=is located within the bottom of the space formed by the inner wall 12, and diametrically opposite this source of heat and formed in the walls of the chamber 10 is a passage 23, formed by a slot extending practically the entire length of the water chamber. This slot permits of the passage of the heat therethrough after it has traversed the wall 12, the heat then entering the passage 14. and being forced downwardly around the outer wall 11 of the chamber '10 as indicated by the arrows on Fig. 3 of the drawings. lFo'rmed within the bottom of the casing 13 is a longitudinally disposed passage 24, which communicates at the rear. of the casing with a smoke stack 25. The rear end wall 26 of the water chamber 10 is also spaced in the rear wall 27 of the casing to 7 provide a passage 28, along whichthe heat will pass in its passage to the smoke stack 25. It will thus be seen that the course of;

the draft directs the heat. units around all of the inside and outside walls of the water chamber, heating the water thereinzin a I ,The ram. a r m vab y m d short space of time and resulting in a great' saving of fuel The walls of the water chamber maybe so regulated as to cause" .steam to be uiekly generated.

sufficient size to permit ofthe movement=of the Water chamber. Carried by this plate andextending into the. chamben 10 is an annular fiangeBzZ: Also formed within the plate 3l is a fuel opening 33,- whichis closed by a door'34; Iioeated'beneath this fuel opening is adoor 35, provided" for the convenient removal of the ashes. Extending through the plate 3-1, preferably at each side ofthe-door 35'isan' airor steam pipe 36, which extends along the under: side of the grate 21', in order to provide a forced draft forthefire ater is supplied to the cham ber' 10 :through the medium of aifilling pipe 37, which communicates- With the said chamberfrom eaohside of the longitudinally disposedpassage 28 asshown .in Figs. l'and5 ofthe drawings. This pi'pe37 is-formed' sections, so that the upper section thereof may be removed to permit of the removal of the water chamber.

Fhe front wall'of the boiler casing mayibe provided with the usual steam and air gages and safety-guide.

It is thought that from the foregoing d'eseription when taken in connection with the Copies. of :thisipatnt may beobtained for accompanying: drawings; the construction,

7 nperatlon and advantages of the invention Will be apparent, The right is reserved to make such elianges' in the form and proportion thereof as will fall within the scope of the claim hereto appended.

Hayingdescribed the invention what is claimed is:

Asteam boilerSe'omprising an outer cylindrical casing, a lower longitudinally extend ing passage projecting from and-oommunh eating with the interior of the casing at the bottom thereof,- a vertically disposed outlet flue communicating with -oneend of said passage. a Water chamberv formed ofinner and 1 outer spaced walls arranged concentri- Cally with and spacedfrom-the-inner wall of 'the casing to provide a==heat circulating bottom, communicating:with the lower longitudinal passage, eentral heating chamfber formedi'by :the inner wall of: the: water chamber, an upper longitudinally disposed passage extending through the upper portion of the waterchamberto establishlcommuni'eation betweenxthe heating chamber and the heat circulating :chamb er' and a vertically disposed passagei-formed'by spacing the rear wall of: thewater chamber from the rear Wall 'ofethe casing for establishing communication between the heating chamber andthe flue through the upper longitudi, nally disposedpassage.
